Description

Technical Field

[0001] This invention relates to the field of container technology, and more particularly to a modular mobile container. Background Technology

[0002] Modular special containers refer to integrated functional units that are prefabricated and integrated into the container body based on the standard container structure and through the modular design concept, forming an integrated functional unit that can operate independently, be plug-and-play, and can be flexibly combined and deployed.

[0003] Traditional shipping containers are large in size and require external bases to move. The installation between the container and the base is time-consuming, and the terrain can easily cause uneven positioning of the container during movement and positioning, which may even affect the use of the machinery inside the container. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of traditional containers in the prior art, such as cumbersome movement and uneven positioning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular mobile container, comprising a container body and a mobile base, wherein a leveling platform is provided on the top of the mobile base and a connecting base is provided on the top of the leveling platform, the container body is mounted on the top of the connecting base, two sets of Mecanum wheels controlled by independent motors are mounted on the mobile base, and multiple sets of negative pressure suction cups driven by hydraulic cylinders are fixedly mounted on both sides of the mobile base for positioning the mobile base, and further comprising: The transmission assembly installed on the leveling platform can be independently controlled in both directions. The two leveling components installed between the movable base and the leveling platform, together with the transmission component, enable the lifting and tilting control of the leveling platform; The quick-release assembly installed on the connecting base enables quick separation between the container body and the connecting base.

[0006] In at least some embodiments, the transmission assembly includes a bidirectional hydraulic cylinder, friction plates, a transmission shaft, and a drive motor. Both telescopic ends of the bidirectional hydraulic cylinder are fixedly connected to a movable collar that is slidably connected to the movable base. Two friction plates are mirror-image arranged. A driven bevel gear is fixedly mounted on the transmission shaft. The drive motor is fixedly mounted on the movable base. An active bevel gear that meshes with the driven bevel gear is fixedly mounted on the output end of the drive motor.

[0007] In at least some embodiments, a spline sleeve is fixedly installed on the back of the friction plate, and the spline sleeve is rotatably inserted into the moving collar. The transmission shaft is rotatably installed on the moving collar, and spline bars adapted to the spline sleeve are provided at both ends of the transmission shaft to ensure that the friction plate does not interfere with its rotation during axial movement.

[0008] In at least some embodiments, two solenoid valves are installed on the bidirectional hydraulic cylinder to achieve mode switching between bidirectional telescoping and unidirectional telescoping of the bidirectional hydraulic cylinder.

[0009] In at least some embodiments, the leveling component includes a sliding seat and a lifting frame. The sliding seat is fixedly installed on the top of the moving base. A lead screw is rotatably installed on the sliding seat. One end of the lead screw is fixedly installed with a friction disc. A slider is slidably installed on the sliding seat. A lead screw pair threadedly adapted to the lead screw is fixedly welded on the slider. The lifting frame is in the shape of a "day" and is rotatably installed between the slider and the leveling platform. A connecting rod for limiting is rotatably connected between the lifting frame and the moving base.

[0010] In at least some embodiments, support balls are provided between the leveling platform and the connecting base. First adjusting screws are threadedly installed at the four corners of the leveling platform. A universal joint is installed between one end of each first adjusting screw and the connecting base.

[0011] In at least some embodiments, the quick-release component includes an unlocking plate and a locking pin. The unlocking plate is arranged between the leveling platform and the connecting base. Multiple guide rods are fixedly welded on the top of the unlocking plate. The unlocking plate is vertically slidably installed on the connecting base through the guide rods. A second adjusting screw threadedly connected to the connecting base is rotatably installed on the top of the unlocking plate.

[0012] In at least some embodiments, buckles are movably inserted in an annular array on the locking pin, and springs are installed between the buckles and the locking pin. A plurality of locking pins are provided and are all fixedly installed on the bottom of the container body. Rotating the second adjusting screw to drive the unlocking plate to rise will press back the buckles to unlock the locking pins.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In the present invention, through the unique design of the quick-release component, one-key locking and release can be achieved between the container body and the moving base, greatly simplifying the hoisting and fixing processes, improving the modular deployment efficiency, highly integrating functions such as movement, temporary fixing, dual-mode leveling, and quick docking in a moving base, and this chassis can be quickly combined with a standardized container body to transform it into a modular functional unit that can move, self-level, and be plug-and-play, significantly enhancing the application flexibility and response speed of special containers.

[0014] 2. In this invention, the transmission component and the leveling component work together to innovatively achieve two leveling modes. In the "synchronous mode," the leveling platform can be driven to rise and fall rapidly for height adjustment. In the "independent mode," the height of the two sides of the platform can be adjusted differently to achieve high-precision leveling. Furthermore, the posture of the connecting base can be further fine-tuned by manually adjusting the four first adjusting screws to ensure that it is completely in contact with the bottom surface of the container above, eliminating local stress and achieving final precision leveling. This design can efficiently cope with complex and uneven ground and ensure the stability of the equipment inside the container. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Implementation examples, based on Figures 1-8 The modular mobile container provided in this embodiment of the invention includes a container body 1 and a mobile base 2, such as... Figures 1-3 As shown, the movable base 2 has a leveling platform 4 on top, and a connecting base 6 on top of the leveling platform 4. The container body 1 is installed on top of the connecting base 6. Two sets of Mecanum wheels 201 controlled by independent motors are installed on the movable base 2. Multiple sets of negative pressure suction cups 202 driven by hydraulic cylinders are fixedly installed on both sides of the movable base 2 for positioning. It also includes a transmission assembly 3 installed on the leveling platform 4. The transmission assembly 3 can be independently controlled in both directions. Two leveling assemblies 5 installed between the movable base 2 and the leveling platform 4 are connected by... The transmission assembly 3 is used to control the lifting and tilting of the leveling platform 4. The quick-release assembly 7 installed on the connecting base 6 enables quick separation of the container body 1 from the connecting base 6. During operation, the entire device is first moved to the target position by the Mecanum wheel 201. Then, the negative pressure suction cup 202 is activated to adhere to the ground for initial fixation. Subsequently, depending on the flatness of the ground, the transmission assembly 3 and the leveling assembly 5 are activated to adjust the leveling platform 4 horizontally. Finally, the quick-release assembly 7 is used to securely install the container body 1 onto the leveled connecting base 6.

[0020] like Figure 4As shown, the transmission assembly 3 includes a bidirectional hydraulic cylinder 301, a friction plate 302, a transmission shaft 303, and a drive motor 304. Both telescopic ends of the bidirectional hydraulic cylinder 301 are fixedly connected to a movable collar 306 that is slidably connected to the movable base 2. There are two friction plates 302 arranged in a mirror image. A spline sleeve 305 is fixedly installed on the back of the friction plate 302 and is rotatably inserted into the movable collar 306. The transmission shaft 303 is rotatably installed on the movable collar 306. Both ends of the transmission shaft 303 are provided with spline strips that are adapted to the spline sleeve 305 to ensure that the friction plate 302 does not interfere with its rotation during axial movement. A driven bevel gear 307 is fixedly installed on the transmission shaft 303. The drive motor 304 is fixedly installed on the movable base 2. An active bevel gear 308 that meshes with the driven bevel gear 307 is fixedly installed at the output end of the drive motor 304. The drive motor 304 drives the transmission shaft 303 to rotate through the active bevel gear 308 and the driven bevel gear 307. The two friction plates 302 are located on the outside of the friction disks 504 of the two leveling components 5. By controlling the extension and retraction of the bidirectional hydraulic cylinder 301, the two moving collars 306 and the friction plates 302 on them can be driven to move closer to or further away from the corresponding friction disks 504 at the same time, thereby realizing the engagement or separation of the two friction plates 302 with the two friction disks 504. Two solenoid valves are installed on the bidirectional hydraulic cylinder 301 to switch between bidirectional and unidirectional extension / retraction modes. When the platform 4 needs to be leveled and raised synchronously for coarse adjustment, the bidirectional hydraulic cylinder 301 is controlled to extend synchronously in both directions, so that the two friction plates 302 simultaneously press against the two friction discs 504. At this time, the drive motor 304 starts, and the power is transmitted synchronously to the lead screws 503 of the two leveling components 5 through the transmission shaft 303, so as to realize the synchronous lifting and lowering of the platform. When the platform needs to be tilted and finely adjusted, the bidirectional hydraulic cylinder 301 can be controlled to extend and retract unidirectionally (for example, only the left side extends), so that the left friction plate 302 presses against the left friction disc 504, while the right friction plate 302 separates from the right friction disc 504. At this time, the drive motor 304 works, only driving the left leveling component 5 to move, while the right side remains stationary, thereby realizing the tilting and leveling of the platform.

[0021] like Figure 5 and Figure 6As shown in the figure, the leveling component 5 includes a sliding seat 501 and a lifting frame 502. The sliding seat 501 is fixedly installed on the top of the moving base 2. A lead screw 503 is rotatably installed on the sliding seat 501. One end of the lead screw 503 is fixedly installed with a friction disk 504. A slider 505 is slidably installed on the sliding seat 501. A lead screw pair 506 that is threadedly adapted to the lead screw 503 is fixedly welded on the slider 505. The lifting frame 502 is in the shape of "day" and is rotatably installed between the slider 505 and the leveling platform 4. A connecting rod 507 for limiting is rotatably connected between the lifting frame 502 and the moving base 2. Among them, when the power of the transmission component 3 is transmitted to the lead screw 503 through the engagement of the friction plate 302 and the friction disk 504, the lead screw 503 rotates. The lead screw pair 506 that is in threaded cooperation with the lead screw drives the slider 505 to move linearly along the sliding seat 501, thereby pushing or pulling one end of the lifting frame 502. Under the drive of the slider 505 and the limit of the connecting rod 507, the lifting frame 502 generates a height change, and then jacks up or pulls down the corresponding side of the leveling platform 4, realizing the function of large-amplitude inclination leveling.

[0022] As Figure 7 shown in the figure, a support ball 601 is provided between the leveling platform 4 and the connecting base 6. First adjusting screws 603 are threadedly installed at the four corners of the leveling platform 4. A universal joint 602 is installed between one end of the first adjusting screw 603 and the connecting base 6. Among them, the support ball 601 serves as the main support point, allowing the connecting base 6 to have a certain degree of swing freedom relative to the leveling platform 4. After the leveling platform 4 is adjusted to be horizontal by the leveling component 5, the four first adjusting screws 603 can be manually fine-tuned to further fine-tune the posture of the connecting base 6, ensuring that it completely fits the bottom surface of the container body 1 above, eliminating local stress, and realizing the final fine leveling.

[0023] As Figure 8As shown, the quick-release assembly 7 includes an unlocking plate 701 and a locking pin 702. The unlocking plate 701 is located between the leveling platform 4 and the connecting base 6. Multiple guide rods 703 are fixedly welded to the top of the unlocking plate 701. The unlocking plate 701 is vertically slidably mounted on the connecting base 6 via the guide rods 703. A second adjusting screw 704, which is threadedly connected to the connecting base 6, is rotatably mounted on the top of the unlocking plate 701. The locking pin 702 has a ring array of movable buckles, and springs are installed between the buckles and the locking pin 702. Multiple locking pins 702 are provided and are all fixedly mounted on the bottom of the container body 1. Rotating the second adjusting screw 704 unlocks the mechanism. When plate 701 rises, it presses back the latches to unlock the locking pins 702. During installation, the container body 1 is hoisted onto the connecting base 6, and multiple locking pins 702 at its bottom are inserted into the corresponding holes of the connecting base 6. The latches on the locking pins 702 pop out under the action of springs and lock into the lower edge of the holes in the connecting base 6, achieving quick locking. When disassembly is required, simply rotate the second adjusting screw 704 to move the unlocking plate 701 upward. The upper surface of the unlocking plate 701 abuts against the latches of all the locking pins 702, pressing them back into the locking pins 702, releasing the locking effect of the latches, and the container body 1 can be hoisted away, achieving quick assembly and disassembly.

[0024] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
